I just replied to your identical separate post, as follows:
I don't know whether a wifi dongle will work with the box. But essentially it is an ethernet box. But they provide two wifi extenders with the package, and free of charge. This worked well in my case, as my modem is literally at the other end of the house to the TV and needed the boost. I got a good signal and clear image on TV most of the time, but still got the same sorts of dropouts and lost connections that many others complain about here -- usually about one a night.
Wiring the house, as suggested above, is not IMHO a viable solution in this day and age. Using the house electrical wiring with devices designed for this, is an interim solution, but expensive, in the sense that you would have to buy those devices. As I say, Vodafone only supply wifi extenders. One is plugged in by ethernet cable to the modem, and the other placed near the TV and connected to the TV via ethernet cable too. So the same effect is achieved. But the box itself remains stubbornly not in itself wifi...
